Abstract

Flat-panel imaging arrays fabricated from hydrogenated amorphous silicon (a-Si:H) are being developed for application in diagnostic x-ray imaging. The potential performance of such imagers is analyzed by means of modeling the imaging system as a cascade of distinct gain and spreading stages. The relative number of image quanta at each stage in the system is represented in a quantum accounting diagram (QAD), and the detective quantum efficiency (DQE) of the imaging system under radiographic, fluoroscopic, and mammographic conditions is calculated. Such an analysis provides a means of quantitatively evaluating and optimizing imager performance for a given application.
